library(readxl)
bist <- read_excel("A7.xlsx", sheet=1)

bistRE <- bistOrder[c(293:295),]
bistREorder <- bistRE[order(as.numeric(bistRE$FA)),]
bistREorder$FA <- as.numeric(bistREorder$FA)
s <- strsplit(bistREorder$COMPANY, " ")
x1 = lapply(s, function(x) x[[1]])
RE <- bistREorder
rownames(RE) <- unlist(x1)
par(mai=c(1,2,1,1))
barplot(log(RE$FA), horiz=T, names.arg=rownames(RE), las=1,
